Rendering to /dev/null by a call to .write causes an error. Calling .render directly is simpler and fixes the error.

Python 2.7 EOL is arriving on 2020-01-01: https://pythonclock.org/
This will allow us to use Python 3 only libraries, like python-barcode,
which can maintain a reduced, simpler codebase, due to only one version
to support.
Closes#371.
Signed-off-by: Romain Porte <microjoe@microjoe.org>
* add a method to check barcode code format
ensure that the code to print is compatible with the ESC/POS formats and
also automatically check this format before printing (barcode() method).
* rewrite test using pytest's parametrize functionality
* add test for the 'check' argument
* update authors list
This was tested on ZJ-5890 with success. By default centering is
deactivated for backward compatibility. Trying to center a QR code in
native mode will raise an exception as we do not know ATM if the native
rendering is centered by default or not.
* Added basic tests for center feature
* Check image size before centering
The DLE EOT command allows querying the status of several features of
the printer.
Added to the online/offline status developed in #237, this commit adds a
paper sensor querying.
Tested with an Epson TM-T20II, which only has an end-paper sensor. The
near-end paper sensor should be tested with a compatible printer.
However, the implementation is quite straight-forward.
The changes done in this commit should help with the open issues:
#5, #27 and #161.
The old implementation lacked the NUL char at the end of the command, as
defined on the Epson ESC/POS Reference Guide (see
https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=53
). Also, the horizontal tab control character (CTL_HT) shouldn't be
there.
This implementation allows setting up to 32 tabs with a given tab width.
Both values are checked to be in the valid ranges defined on the guide.
Also, the TabPosError exception text has been rewritten to define the
stated above.
